Category:Abilities that affect appearance of wild Pokémon

These are Abilities that affect what kinds of Pokémon appear under certain conditions; for example, from Pokémon Emerald onward, Sand Veil halves the probability of encountering wild Pokémon while in a sandstorm if the Pokémon with it is in the first place in the party. These Abilities' effects activate only if the Pokémon with the Ability is leading the party.
